How are aluminum castings different from wrought aluminum products?

The primary difference between aluminum castings and wrought aluminum products lies in how they are shaped and processed to achieve their final form.1

• Aluminum Castings: These are produced by pouring molten aluminum alloy into a mold, where it solidifies into the desired shape. Common casting methods include sand-casting, permanent-mold-casting, and die-casting. The metallurgical structure and properties of these parts are significantly influenced by the specific casting technique used and the rate at which the metal cools.12
• Wrought Aluminum Products: These are created by first casting aluminum into intermediate forms, such as cylinders or rectangular blocks, which are then mechanically worked—or "wrought"—into final products. Common wrought forms include sheet, plate, forgings, and extrusions.13

While both categories utilize alloying elements to enhance performance, their production paths differ: castings move directly from a molten state into a final geometry, whereas wrought products undergo subsequent mechanical deformation to achieve their final shape and desired material properties.132
